Is it A? Smoking by itself can induce snoring? A says stress induces both snoring and smoking, so stress can cause snoring?

or is this one just too out of scope?

B: almost like A, but doesn't connect obesity to snoring so I say out.
E: throat problems aren't said to cause snoring but snoring and smoking causes throat problems.

Tough choice between C and A, both look lovely.
I went with A for the reason that C is the opposite of what is being said. A points out that stress is the cause, not smoking.
D is not correct because the stem said it snoring is not common and therefore, this is already true.

i get A because if you look what the author hypothesizes "smoking by itself can induce snoring." A says that stress also induce snoring

A - is the right answer. If stress is the cause then weakens the Conclusion
B - Irrelevant
C- Strengthens the Conclusion
D - Irrelevant
E - Irrelevant

(D) does cast doubt.
Hypothesis: Smoking by itself can induce snoring.
Weaken: Most smokers do not snore.
I don't understand why it is irrelevant or does not add up. Don't you think that if it is true that most smokers do not snore, how can smoking induce snoring???
IMO, (D) is a potential choice and stacks up well against (A).

i do not think D is a good answer because if you look at the beginning snoring is "not common" in general - for smokers and nonsmokers, so D is stating the obvious from what we are given

very tough question. the fact i like b scares me, considering no one else picked it. it does seem that its not apropos of the argument intially but i think it is.

mainly, the argument that smoking is the reason behind the fact more smokers snore than non smokers can best be refuted by showing a relationship between people who smoke and another ailment; such as obesity; that itself might be the reason behind the increased odds of snoring.

It's A. A successfully explains why people smoke and snore by showing a relationship that isn't "Smoking causing Snoring"

B is irrelevant because it makes no claim about the relationship between smoking and snoring.

C and D are immaterial in this argument because it makes no statement about the increased chances of being a smoking snorer

That was a very good point. I get it now. Thanks for the clarification.

I got completely stumped on this one. Good explanation.
